MACHINE FOR WRITING A PLURALITY OF SIGNATURES.

Application filed November 22, 1927. Serial No. 234,967.

The present invention relates to improvements in machines forsimultaneously writing a plurality of original signatures,-the inventionbeing particularly directed to the means for mounting the writing pensupon the pen bars of such machines. 7

The mounting of the fountain pens or other writing members upon the penbars of a plural writing machine mustaflord an independent yield foreach writing member so that all of the writing members will actuniformly irrespective of any slight irregularities in the surface ofthe checks or I other documents being inscribed, also there must beconvenience for removing the pens from the pen bars for readily fillingthe pen barrels and such removability must provide for the return of thepens to their accurately adjusted operative position upon the pen bars,and finally it is very desirable to include in theinouniting for themaster pen means for readily adjusting the degree of yield of that pento suit the touch and style of writing of individual operators.

These desirable characteristics are included in the present invention inwhich each of the pens or Writing members has adjustably secured to it aclamping yoke formed with a transverse bearing socket designed toreceive a bearing pin or trunnion projecting laterally from an angularbracket that is adjustably mounted upon the pen bar. This bracket uponthe pen bar is formed with two laterally projecting integral lugs orshoulders between which the pen supporting pin or trunnion projects, andby which the pen clamp carrying the pen is limited in its rocking moticnupon the pin. or trunnion. One of these integral lugs or shoulderscarries a small leaf spring which rests against the'rear faceof the penclamp above .the

7 pin or trunnion andyieldingly holds the clamp in engagement with theother lug or shoulder, and yields more or less during the witingoperation to ensure uniformity of action of the individual pens. Thiscushion: ing leaf spring serves, an additional function as a delicatespring latch for holding the. pen clamp in position upon the pin ortrunnion, the ,face' of the clamp having a slight rib .or projectionwhich rests normally in a groove or depression in the face ofthe springfor holding the clamp in position. This combined cushioning and latchingspring enables an operator .to slip the clamp off of the journal pin ortrunnion for the convenience of refilling of the pen, it beingunnecessary to remove the clamp from the pen for this refillingoperation whereby the pen may be quickly returned to operative positionin its exact adjustment after it has been filled.

The pen mounting just described applies to all of the pens of a pluralwriting machine, whether the machine be a large machine of two'or morepen bars and a large number of Writing membersor the simpler form ofmachine in which there is only one pen bar mounted upon properlysupported and poised pantographic arms. lnaddition to these features,the mounting for the master pen which is-especially observed anddirected by the operator, ispreferably provided with an adjusting screwacting upon the cushioning and latching springto :take up more or lessof the yield of the spring so that the operator can readily effect anadjustment to secure the degree of yield that he prefers. v

In order that the invention may be fully understood it will first bedescribed with reference to the accompanying drawings and the patentablenovelty more particularly pointed out in the annexed claims.

In said drawings:

Figure 1 is a plan view of a pantographicall mounted pen bar of a pluralwriting machine embodying the pen mountings of the present invention;

Figure 2 is a side elevation of the same;

Figuretl is an end elevation, partly in transverse section, of the same;

Figure 4 is a detail transverse sectional view of one of the improvedpen mountings;

Figure 5 is a detail horizontal sectional view of the same Figure 6 is adetail perspective view of the master pen mounting showing the pen clampseparated from the supporting bracket of the penjbar.

The accompanying drawings illustrate the present invention as applied toa multiple writing machine of the type covered by Patent No. 1,080,347,dated December 2, 1913, but .I would have it understood atthe outsetthat this invention is not limited to this I specific type of machine,but is applicable to' other forms of multiple Writing machines in whicha pen bar is mounted for universal horizontal movement above a writingbed or table; V

In the particular type Ol lflflCllllle 1llus= tratedjapenbar, 18 ofT-shaped cross-section is" suitably huiig for universal horizontalmovementon apa-ir or parallel links 20, the mounting of which willbeclear from thelde scription and illustration in the Patent No.

The

flange T101 carries two. set screws 103 which engage the longitudinalslot 56 in the pen bar 18'and serve toclamp the bracket in the desiredadjusted positionupon the pen bar.

Each pen 'or writing member has adjustably secure'dupon itsfb'arrel apen clamp conslstmg of a'yoke and a strap 116 secured to the yoke byscrews 117 and confining the barrel of the pen or writing member betweenthem, I This-'yoke115 of the pen clamp I r is bored transversely at 118to receivethe pin or trunnion- 102. of the bracket 100, the

inner face of yoke 115 being properly shaped tofit snugly'against theouter-face of bracket 100 between lugs orsho'uld'ers 105,106.- he

pen clamp yoke is slightly-thinner nan'the width of .the channel' l07between flugs or flanges 105, 106, whereby the pen clamp can rock toalimited degree upon the pin or trunnion 102. A small dug or projection120 on the rear face of the'pen clamp yoke 115 is 'designedto restin-tlie groove or de pression 110 of;spring 108 to constitute a delicatelatch for maintaining the pen clamp in its operative position upon thepin or trunnion 102. In this position the spring 108 tends to hold thepen clamp pr d Wamuy against the lug or flange 105 of bracket100, butyields in the writing opera- 7 tion under-pressure o't the-operator hepen moves over-slight inequalities in he surface of the documents beinginscribe he" above described pen" mounting i common to all ofthepensofthe plural writ ing machine. In additionto the described features,[the mounting for the master pen or that nearest the pilot handlebywhich the machine 1soperated, is preferably provided With anadditlonal ad usting screw shown in detail of Figures '5 and 6 of thedrawing, said screw. passing through the lug orflange 106- andengagingthe leaf spring 108 so that the yield of "this spring upon thepen mounting for the master pen can be regulated to a nicety to suitthe'touch and manner of writing ofthe operator.

- In addition to the advantageous yielding mounting'for 'the pensOtwriting-members in a plural writing machine, the'improved pen mountingotlersmeans tor the readyremo'val of the pens from their mounting forthe purpose of filling when thewritingpens are, as usual, 1'11 theformof fountain pens, The
